datasetGeometryProperty<
T>(dataset): keyofT
Extract the geometry property name directly from a dataset.
Type Parameters
T
T
The expected feature type with typed property keys
Parameters
dataset
The dataset to extract geometry property from
Returns
keyof T
The geometry property name as a key of T
Remarks
Composed lens that navigates: dataset → metadata → geometryProperty
Example
type Feature = { id: number; location: Point };
const geomKey = datasetGeometryProperty<Feature>(dataset); // 'location'
const coords = feature[geomKey];
